  <title>Wildland Fire Perimeters (firep23_1)</title>
  <abstract>Version Information
The data is updated annually with fire perimeters from the previous calendar year.
Firep23_1 was released in May 2024. Two hundred eighty four fires from the 2023 fire season were added to the database (21 from BLM, 102 from CAL FIRE, 72 from Contract Counties, 19 from LRA, 9 from NPS, 57 from USFS and 4 from USFW). The 2020 Cottonwood fire, 2021 Lone Rock and Union fires, as well as the 2022 Lost Lake fire were added. USFW submitted a higher accuracy perimeter to replace the 2022 River perimeter. A duplicate 2020 Erbes fire was removed. Additionally, 48 perimeters were digitized from an historical map included in a publication from Weeks, d. et al. The Utilization of El Dorado County Land. May 1934, Bulletin 572. University of California, Berkeley. There were 2,132 perimeters that received updated attribution, the bulk of which had IRWIN IDs added. The following fires were identified as meeting our collection criteria, but are not included in this version and will hopefully be added in the next update: Big Hill #2 (2023-CAHIA-001020). 
YEAR_ field changed to a short integer type. San Diego CAL FIRE UNIT_ID changed to SDU (the former code MVU is maintained in the UNIT_ID domains). COMPLEX_INCNUM renamed to COMPLEX_ID and is in process of transitioning from local incident number to the complex IRWIN ID. Perimeters managed in a complex in 2023 are added with the complex IRWIN ID. Those previously added will transition to complex IRWIN IDs in a future update.
If you would like a full briefing on these adjustments, please contact the data steward, Kim Wallin (kimberly.wallin@fire.ca.gov), CAL FIRE FRAP.
_______________________________________________________________
CAL FIRE (including contract counties), USDA Forest Service Region 5, USDI Bureau of Land Management &amp; National Park Service, and other agencies jointly maintain a fire perimeter GIS layer for public and private lands throughout the state. The data covers fires back to 1878. 
Current criteria for data collection are as follows:
CAL FIRE (including contract counties) submit perimeters ≥10 acres in timber, ≥50 acres in brush, or ≥300 acres in grass, and/or ≥3 damaged/ destroyed residential or commercial structures, and/or caused ≥1 fatality.
All cooperating agencies submit perimeters ≥10 acres.

Discrepancies between wildfire perimeter data and CAL FIRE Redbook Large Damaging Fires
Large Damaging fires in California were first defined by the CAL FIRE Redbook, and has changed over time, and differs from the definition initially used to define wildfires required to be submitted for the initial compilation of this digital fire perimeter data. 
In contrast, the definition of fires whose perimeter should be collected has changed once in the approximately 30 years the data has been in existence. Below are descriptions of changes in data collection criteria used when compiling these two datasets. 
To facilitate comparison, this metadata includes a summary, by year, of fires in the Redbook, that do not appear in this fire perimeter dataset. It is followed by an enumeration of each “Redbook” fire missing from the spatial data. 
Wildfire Perimeter criteria:
~1991: 10 acres timber, 30 acres brush, 300 acres grass, damages or destroys three residence or one commercial structure or does $300,000 worth of damage 
2002: 10 acres timber, 50 acres brush, 300 acres grass, damages or destroys three or more structures, or does $300,000 worth of damage
~2010: 10 acres timber, 30 acres brush, 300 acres grass, damages or destroys three or more structures (doesn’t include out building, sheds, chicken coops, etc.)
Large and Damaging Redbook Fire data criteria:
1979: Fires of a minimum of 300 acres that burn at least: 30 acres timber or 300 acres brush, or 1500 acres woodland or grass
1981: 1979 criteria plus fires that took ,3000 hours of California Department of Forestry and Fire Protection personnel time to suppress
1992: 1981 criteria plus 1500 acres agricultural products, or destroys three residence or one commercial structure or does $300,000 damage
1993: 1992 criteria but “three or more structures destroyed” replaces “destroys three residence or one commercial structure” and the 3,000 hours of California Department of Forestry personnel time to suppress is removed
2006: 300 acres or larger and burned at least: 30 acres of timber, or 300 acres of brush, or 1,500 acres of woodland, or 1,500 acres of grass, or 1,500 acres of agricultural products, or 3 or more structures destroyed, or $300,000 or more dollar damage loss.
2008: 300 acres and larger

Provides a reasonable view of the spatial distribution of past large fires but is in no way complete. Due to missing perimeters (please see Use Limitations) this data should be used carefully for statistical analysis and reporting. Please contact the California Department of Forestry and Fire Protection’s Fire and Resource Assessment Program for a detailed explanation of the limitations of the data. The data is updated yearly in the spring with fire perimeters from the previous fire season. California Fire Perimeters (All): Unfiltered. The entire collection of wildfire perimeters in the database. It is scale dependent and starts displaying at the country level scale.

  <history>Historic Update Information: Firep22_1 was released in April 2023. Three hundred five fires from the 2022 fire season were added to the database (1 from BIA, 8 from BLM, 176 from CAL FIRE, 49 from Contract Counties, 14 from LRA, 8 from NPS, 38 from USFS, and 11 from USFW). The 2021 Dotta (part of Beckwourth Complex), Greenhorn, and Hartman fire perimeters were added. Another 45 fires were added by USFW from 2015-2021. The 1988 Hessel fire was added in LNU. The 2019 Cave fire was replaced with a more detailed perimeter submitted by Santa Barbara County. The 2017 Hudson, 2017 Lake, 2017 Jones, 2017 "37", 2019 Tucker, and 2019 Refuge perimeters were replaced with imagery digitized perimeters from USFW. Attributes were updated for 32 records. One hundred ten perimeters were removed due to duplication or being completely contained outside of California state borders. The field IRWINID was added to provide a unique ID; fires before 2022 are lacking this attribution (with the exception of those added in this publication where possible). The following fires were identified as meeting our collection criteria, but are not included in this version and will hopefully be added in the next update: 2022 Cable (CAL FIRE, AEU), 2022 All American (BIA, CRA). Firep21_2 was released in October 2022. The fields COMPLEX_NAME and COMPLEX_INCNUM were added to the dataset; historical complex fires were updated as such to the best of current ability. COMPLEX_NAME is for fires that were initially individual fires (with their own name) and then became part of a complex and thus were given a new name. COMPLEX_INCNUM was created for the same reason as COMPLEX_NAME. Ten fires were added (5 CAL FIRE, 5 USDA Forest Service). The 2008 Paradise fire perimeter was spatially adjusted to more accurately account for its location. Six perimeters were removed, becoming a complex. The 1996 Columbia Hill and Shields Camp perimeters were removed due to confirmation of their status of prescribed burn. The 2014 Coffee fire was replaced by a more accurate polygon. Thirty-two records' attributes were updated, mostly CAUSE data from 2019 and 2020. Firep21_1 was released in April 2022. Three hundred seventy-two wildfires from the 2021 fire season were added to the database (21 from BLM, 223 from CAL FIRE, 3 from DOD, 40 from LRA, 15 from NPS, 66 from USFS, 2 from BIA, and 2 from USFW). The following fires were identified as meeting our collection criteria, but are not included in this version and will hopefully be added in the next update: Dotta (part of Beckwourth Complex), Greenhorn, Hartman, Lone Rock, Union, and Nelson. The 1933 Griffith Park fire, 2018 Bridal fire, 2020 Kare fire, 2020 Green fire, 2020 Indian fire, 2020 Tripp fire, 2020 Apple fire, and the 2020 Gulch fire were added. A duplicated 1912 fire was removed, 31 perimeters were replaced with more accurate perimeters, and 6 perimeters’ attributes were adjusted. Firep20_1 was released in April, 2021. Five hundred wildfires from the 2020 fire season were added to the database (12 from NPS, 277 from CAL FIRE, 76 from USFS, 37 from BLM, 3 other). Two previous fires were modified, the 1994 Steckel fire was deleted and the two 1979 Hernadez were merged into one fire. Firep19_1 was released April 30th, 2020. Three hundred twelve wildfires from the 2019 fire season were added to the database (4 from the NPS, 180 from CAL FIRE, 68 from USFS, 21 from BLM). Firep18_1 was released May 1st, 2019. 413 wildfires from the 2018 fire season were added to the database. There are two fires on BIA managed land that do not have 3 letter code identifiers and thus "Unit" was left blank. A hand drawn perimeter of the 1990 San Juan Canyon fire in BEU was submitted by a fire fighter who worked on the fire. The perimeter of the Thomas fire of 2017 was replaced this year by one collected by SBC that is based on someone walking some parts of the perimeter for better accuracy. Firep17_1 was released April 13th, 2018. 612 wildfires from the 2017 fire season were added to the database. Three USFS wildfires from previous years were also added (1 from 2014, and 2 from 2016). Attributes from 3 USFS wildfires were also corrected (Willow 2015, Gilman and Meadow 2016). Two new USFS Forest were added to the domain list of Units (Rogue River-Siskiyou NF &amp; Fremont NF).The Barry Point Fire is now attributed to the Rogue River-Siskiyou, previoulsy it was attributed to other (as a unit). There are two fires for 2018 already in the database. Firep16_1 was released May 4nd, 2017. I 2014 VNC fire perimeter was replaced by a more accurate version. 3 new perimeters from 2014 were added (VNC). A new perimeter from 2013 added. 66 new perimeters from 2015 were added. 92 new perimeters in Marin County, from 1917 to 1934 were added. They were hand drawn by the Marin County fire Chief Garber and digitized and submitted by NPS. 8 duplicate fire perimeters were deleted. Firep15_1 was released June 9th, 2016. The ALARM_DATE and CONT_DATE fields have been changed from STRING fields to DATE fields. In the many cases where only the year of a fire existed (ex. 19170000) the tool couldn't process the data and the entry is NULL. In those cases, the year can be found in the YEAR field. Firep14_1 was released in May, 2015. After release, the NPS supplied corrections for 14 wildfires and 67 prescribed burns. The corrected data was posted to FRAP's data download page as fire14_1 in late May. An effort was made to ensure multipart polygons were standardized throughout the dataset. Firep14_2 was released in July, 2015 to reflect that changes had been made to the original release in late May. Version 14_1 from late May is an exact copy of version 14_2 released in July. </history>

  <constraints type="Limitations of use">This is the most complete digital record of fire history in California. However, it is still incomplete in many respects. Fires are undoubtedly missing or have missing or incorrect attribute data. Some fires are missing because historical records were lost or damaged, were too small for the minimum cutoffs, had inadequate documentation or have not yet been incorporated into the database. For example, the 2008 Lone Pine fire perimeter has never been collected and may never be. 
Other errors with the fire perimeter database include duplicate fires and over-generalization. While the data capture process attempts to identify duplicate fires resulting from multiple data sources (e.g., the USFS and CAL FIRE both captured and submitted the fire perimeter), some duplicates may still exist. Additionally, over-generalization, particularly with large old fires may show unburned "islands" within the final perimeter as burned. Users of the fire perimeter database must exercise caution in application of the data. Careful use of the fire perimeter database will prevent users from drawing inaccurate or erroneous conclusions from the data.</constraints>
